Calculating Equilibrium Concentrations

For the Haber process, N2(g) + 3 H2(g) ⇌ 2 NH3(g), Kp = 1.45 ⇌ 10-5, at 500 ℃. In an equilibrium mixture of the three gases at 500℃, the partial pressure of H2 is 0.928 atm and that of N2 is 0.432 atm. What is the partial pressure of NH3 in this equilibrium mixture?

At 500 K, the reaction 2 NO(g) + Cl2(g) ⇌  2 NOCl(g) has Kp = 51. In an equilibrium mixture at 500 K, the partial pressure of NO is 0.125 atm and Cl2 is 0.165 atm. What is the partial pressure of NOCl in the equilibrium mixture?

(a)        0.13 atm

(b)        0.36 atm

(c)        1.0 atm

(d)        5.1 x 10-5 atm

(e)        0.125 atm.
